The forefield of the Gauli glacier encompasses a picturesque mosaic of bogs and rocks: a typical rock outcrop bog landscape. The Pleistocene glaciations have grinded a multitude of terrain depressions, rounded rock hills and ridges (humps) into the rock. In the terrain depressions a lot of different sized bogs developed. The fens are the most common, they are kept wet by surface water. However, there are also transitional mires, areas with raised bog vegetation and small, almost silted ponds. The flora of the mires is varied and offers a habitat to different animals. In particular, the grass frog is widespread in the forefield of the Gauli glacier. So watch your steps!
